< br />You would think that jumping on a grenade to save the lives of his fellow Marines would be the defining moment of Kyle Carpenter's life. But anyone willing to sacrifice his own life must have had quite the story to tell already. And miraculously, he's survived to tell it. The youngest living Medal of Honor recipient, Kyle can't remember his heroic act. He recounts his life before the grenade, the surreal moments right after the explosion, and the amazing things he's chosen to do with his second chance at life. The author of "You Are Worth It: Building a Life Worth Fighting For," he's chosen to embrace his scars and spread hope and kindness across the nation. And unbelievably, he's grateful for the grenade that gave him the opportunity.
